Objective To study the relationship between cerebral edema and radiofrequency electrode temperature and duration of hyperthermia for treatment of cerebral tumors.
目的研究脑肿瘤热疗中脑水肿与射频电极温度和作用时间的关系。
In radiofrequency ablation, imaging techniques such as ultrasound, computed tomography (ct) or magnetic resonance imaging (MRI) are used to help guide a needle electrode into a cancerous tumor.
在射频消融术中，通过诸如超音波，电脑断层扫描(CT)或磁共振成像(MRI)来帮助指导一个电极针进入癌肿瘤内部。
Once the needle electrode is in place, radiofrequency energy is applied.
当电极针到位，射频能量将释放。
